Example stack trace: return self.cursor.fetchall() File "/Users/mike/analytics/venv/lib/python3.4/site-packages/impala/hiveserver2.py", line 336, in fetchall return list(self) File "/Users/mike/analytics/venv/lib/python3.4/site-packages/impala/hiveserver2.py", line 381, in __next__ self.buffersize) File "/Users/mike/analytics/venv/lib/python3.4/site-packages/impala/hiveserver2.py", line 958, in fetch convert_types=convert_types) File "/Users/mike/analytics/venv/lib/python3.4/site-packages/impala/hiveserver2.py", line 963, in _wrap_results return CBatch(results, schema, convert_types=convert_types) File "/Users/mike/analytics/venv/lib/python3.4/site-packages/impala/hiveserver2.py", line 640, in __init__ for (i, col) in enumerate(trowset.columns)] File "/Users/mike/analytics/venv/lib/python3.4/site-packages/impala/hiveserver2.py", line 640, in <listcomp> for (i, col) in enumerate(trowset.columns)] KeyError: 'MAP'
